CRVS systems play a key role in monitoring and facilitating progress towards the SDGs. As the best source of continuous and up to date information on birth, death, health and population statistics, CRVS is needed to measure a wide range of population-based SDG targets. Legal documentation provided by civil registration systems helps to reduce trafficking, statelessness, sexual exploitation and child marriage. Improving CRVS is also an SDG objective in its own right and is covered by Goals 16.9 and 17.19.
